We're on a quest to unravel the mystery that is the caves beneath Australia's Nullarbor desert. Subscribe to ABC Science RU-vid 👉 ab.co/2YFO4Go
Unique in the world, these are big labyrinthine salt water-filled caves, up to 90 metres below the flat, dry desert surface and extending for kilometres underground. Geologists believe that the Nullabor has been mostly dry since it emerged from the sea 15 million years ago. So are the caves relics of a bygone era, or are the processes that formed them still at work?
